David Sugar will be presenting SIP Witch, the secure telephony portion of the GNU Telephony project, this Saturday at the Southern California Linux Expo (SCALE/8X) (http://www.socallinuxexpo.org/scale8x/). SIP Witch is designed to provide truly liberated and secure telephony over IP networks. David Sugar: Communication Privacy for Free Societies: http://www.socallinuxexpo.org/scale8x/presentations/communication-privacy-fr... "This project will offer the means for anyone to create and deploy network scalable and secure VoIP/collaboration solution to enable privacy without the need for a central service provider or proprietary software to achieve these goals. Our overall vision is to facilitate both solutions that are privately built, such as for organizations that wish to have secure communication as a foundation, and especially which can be autonomously assembled over the public Internet as a full public alternative to Skype using only free software and that depends purely on existing DNS for user lookup, rather than a service provider, and eliminates the use of source secret clients which can of course be compromised."

GNU SIP Witch is our VOIP call, provisioning, and feature server of the GNU Project. GNU SIP Witch supports using secure telephone extensions, for placing and receiving calls directly over the internet, and intercept-free peer-to-peer audio and video extensions. GNU SIP Witch also is being introduced as a desktop VoIP mediation service to enable the construction of participatory bottom-up secure calling networks and to enable replacement of Skype with free software and published protocols. As a desktop mediation service, GNU SIP Witch can solve issues like NAT in one place for all user agents, and offer new ways to route and redirect VoIP much like gstreamer does for desktop media.
